Supercapacitors – FC Series
Performance Characteristics
Supercapacitors should not be used for applications such as ripple absorption because of their high internal resistance
(severalhundredmΩtoahundredΩ)comparedtoaluminumelectrolyticcapacitors.Thus,itsmainusewouldbe
similar to that of secondary battery such as power back-up in DC circuit. The following list shows the characteristics of
supercapacitors as compared to aluminum electrolytic capacitors for power back-up and secondary batteries.

(*1) Aluminum electrolytic capacitors and supercapacitors have limited lifetime. However, when used under proper conditions, both can operate within a
predetermined lifetime.
(*2) There is no harm as it is a mere leak of water vapor which transitioned from water contained in the electrolyte (diluted sulfuric acid). However,
application of abnormal voltage surge exceeding maximum operating voltage may result in leakage and explosion.
